Overview

The DP2VGA3 DisplayPort to VGA adapter lets you connect your DisplayPort-equipped desktop or laptop computer to a VGA monitor or projector, eliminating the expense of upgrading to a DisplayPort display.

The DP to VGA adapter supports resolutions up to 1920x1200 including 1080p ensuring you can convert your DisplayPort video source to work with your VGA projector or display without sacrificing video quality.

For a hassle-free setup the DisplayPort adapter allows for plug-and-play installation with no software or drivers required.

The DP2VGA3 is backed by a StarTech.com 2-year warranty and free lifetime technical support.

When you convert video from a source that uses DisplayPort or Mini DisplayPort to DVI or HDMI (for example, a computer to a monitor), you will need to consider the difference between passive and active adapters.

If the source supports dual-mode DisplayPort (also known as DP++), then you can use a passive adapter because the source can perform the conversion. If the source does not support DP++, then you need to use an active converter, which includes additional chips to perform the conversion.

Thunderbolt ports support DP++ natively. To run multiple monitors from the same computer, refer to the Active Adapters section below.

Passive Adapters

Passive adapters are less expensive since they do not need to include additional chips. A quick way to check whether you can use a passive adapter is to see if the DisplayPort or Mini DisplayPort source has the DP++ symbol above it. The symbol is a D with a P inside of it, with two + signs to the left, one on top of the other.

Active Adapters

Active adapters use additional chips to make the conversion inside the adapter, regardless of whether the source supports DP++. This means that active adapters are more expensive than passive adapters.

If you want to use multiple monitors with the same computer, you should use an active adapter because some video cards cannot run the maximum number of monitors while using DP++. This is especially true if the computer has more than one DisplayPort or Mini DisplayPort connection. Check with your video card manufacturer to confirm which type of adapter you need for the setup that you would like to run.

Note: You should use passive adapters with StarTech.com MST hubs, except when you are converting from DisplayPort to VGA, since that type of conversion requires active adapters. For more information on using adapters with StarTech.com MST hubs, refer to the following FAQ: http://www.startech.com/faq/mst_hubs_passive_vs_active_adapters.

Surface Dock

If you experience issues when you connect passive video signal adapters to the Surface Dock, Microsoft recommends that you use active video signal converters instead. StarTech.com offers an active video signal converter for DVI monitors (MDP2DVIS) and for HDMI monitors (MDP2HD4KS).

Troubleshooting

When you troubleshoot issues with a video adapter, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

Video cables

Video adapter

Video source (such as a DVD player or computer)

Video destination (such as a monitor or projector)

To test your setup components, try the following:

Use the cable, video adapter, video source, and video destination in another setup to see if the problem is with the components or the setup.

Use a different cable, video adapter, video source, and video destination in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

Test each cable individually.

Use short cables when you are testing.

When you test the video source and video destination, it is recommended that you do the following:

Remove the video adapter from your setup and test to make sure that the video source and video destination work together without the video adapter.

Test to make sure that the video source and video destination work together at the resolution that you want to use.

Note: In order for your setup to work properly, the video source, adapter, and destination all need to support the resolution that you are using.
